AUTOMATIC EL (ill whom it ma y coiwecii 5 tented scents Y Be it known that I, Cms'r H. STEYIQK, c

. oitise'ir of the United Stetes, eix'd residing at storia, Lon island, in the county of Q ueehs and tete of New Y rk, have incertain new end use 11 Improve gr Automatic Electric Gas-Drip Alarm evices, of which the following is e specification, such as will enable those skilled in, the art to which it eppertains to maize and use the seine. This invention relates to apparatus or devices for automatically giving'noticeof the collection of condensation-water in at gas pipe or drip cup, in order that the sealing of the drip cup and the consequent cutting 05 of the flow of gas theret ough may be prevented and the object of t e ir ventioii is and with this and other objects in view,

a drip cup 11 of to provide an improved epperetus or device of this class which is simple in copstruction, efiicient in operation,

conveniently applied wherever necessary,

the ix vention consists in a device or apparatus of the class specified, constructed and no crating as hereinafter described end claimed. a

The invention is fully disclosed in the following specification, of which the accompanying drawing forms apart in which the separate parts of my improvement are desigdrawing being a sectional side e vetion of e device or apparatus involving my invention. I

In the practice of my the usual or any preferred construction and with the op osite sides of .which, and preferably near t e top thereof,

the gas supply pipe or main b is connected. The cup at is provlded in the bottom thereof with a, discharge pipe 0 hevin and the topthereof is provide with a cap, cover, or other suitable closure device o3 through which is passed a drip pipe e having a packing c and the pi e 0 extends downwardly to Within a few mches of the bottom of the drip cup. I also provide a drum, box, or casing, f'composed of top'end bottom parts f and 7' between which is see cured a diaphragm 1 material and which divides the drum f into top and bottom chambers f a,nd f, the botand which may be invention, I provide specificat on of teeters; threat.

' noted by suitable reference cheragters, seid a valve. 0 i

composed of flexible Potted he e. is. lei-e.

me awa t swim so; from ste l, he. create with the bottom portion of the drum f at one side theieof and commurricetes with the chtrpb'erj end is provided with a valved. A discharge pi e reconnected with the bottom portion o1 tie drum f and also communicates with the chamber f, and this ipe has an upwardly directed extension 9 .ievin e srcall outlet critics g he drum 1 is provided n with en perture f closed by an insulated the top thereof to cap it o errysoitable construction and through which is passed a vertically movabie rod 41 which also passes through the aperture 1" and downwardly through the diaphragm f to which it is secured at i in any desired scanner. The cap, it is. provided on the top in the operation of this epperetus, the

valve c is open and by reason of the connection with the opposite sides of the cup or of the gassupply pipe or main 5, as shown and described, the gas flows into and through said cup, as will be readily understood, and in this operation, the water of condensation that collects in the main flows into and collects in the bottom of the drip cup 05, as

shown at it. Under normal conditions, the

as will'tiow from the drip cup e through he pipe e and through the bottom chamber f of the drum f and through the ipe-g, and a small amount of this gee wilt dis changed at g and may be ignited, if desired,

and the light thus produced wiil show at all times that the seid apparatus is in working order, and the amount of the water of condensation in the drip cup at is not sufiicient to seal the flow of gas, or cut oif the flow of gas through the ipe e. As. the water of condensation gra uelly rises, however, in the bottom of the cup a, the lower end of the ipe c is sealed, and if this'water is not disc orged or pumped out, the flow of gas I through said pipe e will be out ofi, and escape of as from the drum f throughth'ei pipe 9' wil reduce the pressure below'ther diaphragm f,

t e-c end the rod-i will drop and,

the contact device or devices 11 will come in connection with the cap h, or the contact flange or rim 7& thereof, and the circuit Will be closed through the wires j and j and battery 7c, and the alarm device we will be opererate the apparatus as described, may be fixed at any desired amount by regulating the length of the pipe a, or the depth to which it extends into said cap, and while I shave shown and described the preferred form and construction of my invention, it will be apparent that changes therein and modifications thereof may be made, Within the .scope of the appended claims, Without departing from the spirit of my invention or sacrificing its advantages. 4

Having fully described my invention, What I claim as new and desire tosecure by Letters Patent is 1. In a gas-drip alarm apparatus, a drip cup with which the gas supply main communicates at two points, a drippipe passing downwardly through the top of said cup and terminating above the bottom thereof.

and adapted to be sealed by drip Water as it rises in the bottom of said cup, and means whereby the sealing of said pipe will operate an alarm device.

2. In a gas-drip alarm apparatus, a drip cup with which the gas supply main communicates at two points, a drip pipe extending downwardly into said cup and terminating above the bottom thereof, a box having a horizontal flexible diaphragm forming top and bottom chambers therein and through the bottom portion of which the drip pipe communicates, said bottom portion of said box being also provided with a discharge pipe, and a rod verticallymovable through the top part of said box and secured in said diaphragm, said rod forming part of an open electric circuit adapted to be closed by the vertical moveni'iit thereof, and in which is placed an electric alarm device. V

8. In an electric gas-drip alarm. apparatus, a drip cup with the top portion of which a gas supply main communicates at two points a drlp pipe passing downwardly through, the top of said cup and terdivided by a flexible horizontal diaphragm into top and bottom chambers and with the bottom portion of which said drip cup communicates, a discharge pipe also connected with the bottom portion of said box, a rod zontally by a flexible diaphragm into top m-inating above the bottom thereof, a box 1 and bottom chambers, a rod movable vertically through the top of said box andlsecured. in said diaphragm, and means whereby the rise of drip water in said cup will operate;- said' diaphragm and said rod to close an electric circuit in which is placed anv electric alarm device.

5-. In a gas-drip alarm apparatus, a-' drip cup with which the gas supply main communicates at two. points,a drip. pipe passing into the top portion of said cup and tenthnating above the bottom thereof and'adapted to be sealed by drip water as it rises in the bottom of said cup, and means whereby the sealing of said part will operate an 1 alarm device.

In testimony that I claim the foregoing as my invention I have signed my name in presence of the subscribing; witnesses this 21st day of January 1914.
